UV Light Emitting Diodes (UV LED)

We offer Nikkiso’s advantaged UV-LED products – all with high performance and reliability at an affordable cost. Along with our sglux UV sensors and probes, Boston Electronics now offers the UV industry the best of breed UV detection and light sources.

UV-LEDs are available at standard wavelengths of 265, 280, 285, 300 nm.

Packages include SMD, SMD mounted on carrier boards, TO-46 and TO-46 with lens.

Arrays are also available, see the catalog.

An ideal replacement for mercury lamps, Nikkiso UV-LEDs are earth friendly and can be custom designed for a myriad of applications.

Ultraviolet Disinfection Technology

Ultraviolet (UV) disinfection technology has been the star performer in water and air treatment over the past two decades, due in part to its ability to provide treatment without the use of harmful chemicals.

UV represents wavelengths that fall between visible light and x-ray on the electromagnetic spectrum. The UV range can be further divided into UV-A, UV-B, UV-C, and Vacuum-UV. The UV-C portion represents wavelengths from 200 nm – 280 nm, the wavelength used in our LED disinfection products.

UV-C photons penetrate cells and damage the nucleic acid, rendering them incapable of reproduction, or microbiologically inactive. This process occurs in nature; the sun emits UV rays that perform this way.

UV-LED are used to generate high levels of UV-C photons. The rays are directed at viruses, bacteria and other pathogens within water and air, or on surfaces to render those pathogens harmless in seconds.

UVLED Basics

LEDs are produced by a number of companies globally on wafers that contain up to 40,000 individual LED lights. These lights are measured and categorized according to their characteristics. Each LED device is then packaged to allow electrical connection, thermal management, and physical protection.
